A protocol exception is a one-time, intentional action or process that departs from the IRB-approved study protocol for one participant in the study.

Protocol exceptions must be approved by the IRB prior to implementation of the exception. A departure from the protocol that is submitted to the IRB after the action or process has occurred is considered noncompliance that must be reported to the IRB as new information.

To submit an exception request, submit a modification in ETHOS.
